SPECIFICATION forming part of Letters Patent No. 429,411, dated J' une 3, 1890.

Application filed November 14,1887. Serial No. 255,044. (No model.)

lTo all whom it may concern:

Be it known that I, ROSCOE BEAN, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Pumps, of which the following is a speciiication, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in double-acting forcepumps, the peculiarities of which will hereinafter be more fully described, and pointed out in the claim.

In the accompanying drawings, forming a part of this specification, and on which like reference-lettersindicatecorresponding parts, Figure l represents a vertical sectional view of my improved pump, showing some of the parts in side elevation; Fig. 2, avertical sectional view of the pipe-cap, the water-pipe, the coupling, and the cylinders, and a side elevation of the several other parts thereof, omitting the divided head and handle; Fig. 3, a vertical sectional view of a portion of the water-pipe and the cylinder and of ythe coupling, showing a modification in the construction thereof; Fig. 4, a horizontal section on the line @j y of Fig. 3, looking in the direction of the arrow, of the coupling detached; Fig. 5, a horizontal sectional view of the divided head and pipe-cap on the line m of Fig. l, looking in the direction of the arrow,

Fig. 6, a detail side elevation of the coupling with a portion of the outer cylinder in section; and Fig. 7, a partial section and elevation of theseveral pipes, showing a modiiied form of the cap. r

The letter A designates a platform or wellcnrbing of any approved construction, upon which is mounted the two-part vertically-divided head B, one half of which is removed in Fig. l, so as to show the interior arrangement of the parts. A standard C extends from each of the halves,and together forms a support of the handle D, while the lower ends of said halves are enlarged to form a casing E, as clearly seen in Fig. l. Vithin this casing is suspended a hollow pipe-cap F, consisting of a metallic vessel of suitable dimensions to receive the quantity of water raised by thepump, and of such shape as to conveniently occupy the interior of the casingE, as seen more clearly in Fig. 5. A tubular air-chamber G and a discharge-pipe H, having a spout I, are connected with the pipe-cap F and clamped and held by the two halves of the'head B between their meeting edges. So far as concerns the divided head, per se, I wish to be understood that such is not new. Thus the pipe-cap is sustained within the casing E, and thus a means of connection is established between the discharge-pipe and the water-pipe which delivers the water from the cylinders upward, as

also a means of communication between the air -chamber and the uprising volume of water, whereby an even stream is produced.

A` pipe J is connected with the pipe-cap and with the coupling K, and forms the essential means by which the lower mechanism of the pump is suspended, as also the waterpipe which delivers the water to the hollow pipe-cap. Within the pipe, and extending from the coupling K into and through the pipe-cap, is a tubular piston-rod casing L, whose essential function isthat of avoiding the necessity of a packing-box between the piston-rod and the coupling and between that rod and the said cap. This tubular casing L is connected with the coupling and the pipecap either by being screwed into threaded apertures therein or by being merely passed through smooth apertures and provided with a nut, as seen in Figs. 1 and 2.

The coupling K consists of two segmental parts M and an upper cylindrical sleeve N and a lower-cylindrical sleeve O, to the former of which the pipe .I connects and to the latter of which the outer cylinder connects, asby screw-threads. Water passages or ports P extend through the diaphragm or horizontal wall Q (see Fig. 4L) of the coupling, and serve to forni communication between the cylinders and the interior of the segmental parts M. The wall Q forms a part ofthe shell-like structure of the coupling and occupies the area not occupied by the lower ends'of the segmental parts M, and constitutes a part in which an opening is formed for the reception of the sub-coupling R, by which the inner cylinder is suspended from the cou pling K and within the outer cylinder. The sub-coupling is of two forms, that shown `in Fig. 3 consisting of a tube S and aplug T, screwed togetherl and respectively into said that shown in Fig. 3.

The letters U and V designate, respectively, the outer and inner cylinders, which are so proportioned, relatively, that about one half of the water lifted by the upstroke of the pistons passes into the inner cylinder and the remaining half between the cylinders, whereby on the downstroke of the pistons about the same quantity of the water is forced up as is lifted on the upstroke thereof, the result being a perfectly-uniform delivery of water at the spout.

The piston-rod is designated at IV, and is provided with a lift-piston Xand a force-piston Y of the usual or any approved construction. The rod itself is preferably of tubular form, as seen in Fig. 2, and is provided with an 'opening a below the force-piston for the purpose of constituting an air-chamber to prevent or avoid any tendency t-o pounding The outer cylinder at its lower end is provided with its usual check-Valve b and a lift-pipe c. It will be observed that the inner cylinder terminates below the flange O of the coupling, whereby the comparatively small space at this point is not unduly occupied by the parts, thus leaving ample space for the unobstructed passage of the water. ports P, being of the form shown in Fig. 4- that is, segmental-also allow ample freedom. It will also be observed that the pipe J, being sufficiently large, gives ample passage for the water, notwithstanding the tubular casing Il, and is also large enough to strongly sustain the lower mechanism of the pump and prevent the same from any tendency to sway or rock laterally. Again, the exterior of the p ump is smooth or symmetrical, is devoid of proj ections, and is all within the outer diameter, or does not exceed that diameter, of the cylinder U, whereby the pump is excellently adapted to the purposes of the bored wells, sometimes known by the name of deep wells, by reason of the great depth to which some bored wells are extended. The pipe J is made longer or shorter according to the depth of the well, being in pumps intended for deep wells sufficiently long to bring the cl1eck-valve Z) from twenty-four to twenty-six feet above the surface of the water-supply. The divided head constituting a strong and Again, the

Ying the pump immediately flows back into the lower part of the pump, and is thus pre-4 vented from freezing.

The diameter of the tubular air-chamber G may be varied to suit the work the pump is to do, though it is shown in the present instance as about the same diameter as the discharge-pipe Il. The length of said charnber may also Vary.

In Fig. 7 I have shown the water-pipe J connected to the discharge-pipe and the airchamber by a different form of cap from that shown in the other figures, the dierence being that the cap shown in Fig. 7 is not hollow, as in the other gures. The essential functions of the hollow cap are subserved, however, by the cap F', for I have spoken of the cap F as forming a connection between the discharge-pipe and the pipe which delivers the water from the cylinders as forming a means for communication between the airchamber and the uprising volume of water, and as forming a stanch connection for sustaining the pipe J through the medium of the ai r-chamber and discharge-pipe, and these things are accomplished by the cap F. The cap F is also so located as to be inclosed by the casing E of the. divided head in the same manner that' the cap F is inclosed. Thus the two forms of caps are in all essential details particularly the equivalents ot each other. The attachment of the piston-rod casing to the cap F is also the same as its attachment to the cap F.

It is desirable that the portion of the waterpipe which serves as a support to the cylinders should be comparatively large to afford strength and to prevent the cylinders from swaying, while it is equally desirable that this larger size should terminate about where it is secured at the platform end, and the remainder of the pipe, or that portion called the discharge-pipe, be reduced to a smaller size` so as to avoid lifting so much water before securing a low at the spout, and also to avoid so great an accumulation of water, which, after using the pump, has to flow back below to prevent freezing.

The cap, either form, is used as a means of connecting these two sizes of the waterpipes, and also affords a cover or supporting portion of said pipe.

The diameter and the depth of the hollow form of cap may be varied to suit particular circumstances.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
